Prior to her MMA debut, the manager for Momo issued a statement to the media on her combat sports experience:

“Momo has been training MMA six times a week at least three hours a day ever since when she was in the kindergarten. Momo already had over 100 amateur BJJ, kickboxing, and karate matches, therefore, she has far more experience in combat sports than her upcoming opponent Ms. Momoko Yamazaki. [...] On May 20th, we all strongly believe Momo would beat Yamazaki. I think it’s gonna be a public humiliation for Yamazaki.”
